run-tests: refactor port allocation into functions
Adding a port reservation was too hard and someone did it wrong.
By refactoring, such reservations can be managed more safely.
This also adds documentation so that the next person who tries
is more likely to update all the places correctly.
Note that in this commit the reservation and consumers do not
match, that will be fixed in the next commit.
